Hi all, I have checked all the code of realclass system, founding the following libraries are conflicted with ASL：
a) libavcodec and libavformat (from ffmpeg 0.4.8). Solved by recompiling ffmpeg 0.4.9 as LGPLed, to adapt to the system, the video codec is changed from MPEG1 to MPEG4 b) 1394dv libraries (one of them is GPLed) . Since webcam is good for the system, we just delete the 1394dv support. c) arts library(GPLed). I have finished using SDL to replace artsd to play audio stream, but the sound effect is not good (noise exist). d) oss APIs (soundcard.h) I have seen the declaration in soundcard.h and thought it's totally free to use. Also I have searched the oss forum and found different opinions on the license of soundcard.h. I am still a little confused. So I think realclass system have no license problems now. I am trying to solve the noise problem of SDL, once it is finished, we can start to prepare for the release. Regards, Arthur
